The iconic educational program for Davidson was originally released on 5.25" disk in 1983, but was also released on 3.5" later on, making disk swapping unnecessary.

As it turns out, Davidson's earlier and original releases of their classics Math Blaster, Alge Blaster, Spell It!, Grammar Gremlins and Word Attack were also available on 3.5" disk release - which is convenient as most required disk flipping to access more of the games from the original 5.25" disk releases.
